3 Claims.

This invention relates more particularly to means for washing orcleaning drinking vessels, such as tumblers, liquor glasses, mugs andthe like, that are used in drinking parlors and at soda fountains.

The principal object of the invention is to provide improved andsimplified means whereby such work can be done rapidly, thoroughly andeconomically. Other objects of the invention will 19 appear from thedisclosure herein.

The invention is embodied in the example herein shown and described, thefeature of novelty being pointed out in the claims.

In the accompanying drawings- Figure 1 is an elevational view of themechanism according to the invention with some parts omitted and brokenout for the sake of clarity.

Fig. 2 is a plan view from the line II--II, Fig. 1, showing the watersupply means and control means therefor.

Fig. 3 is a top plan view looking at the turn table and brushes carriedthereby.

Fig. 4 is a detail sectional view, on the line IV-IV, Fig. 1, of thepedestal and a portion of the water conducting means.

Fig. 5 is an elevational view of a pair of the brushes shown in thelower portion of Fig. 3 and their mountings in the rotatable table.

Fig. 6 is a detail view partly in section of the valve and means foractuating the same to control the water supply.

Fig. 7 is a detail, in plan view, of the mountings for the group ofbrushes shown at the left hand side of Fig. 1.

In the views, and referring more particularly to Figs. 1 and 4, thecharacter l designates a suitable pedestal or stand having at its centera hollow member or chamber H from which latter is an upwardly extendingtubular bearing l2. On the said bearing i2 is a rotatable sleeve 13having fixed on its lower portion a cam 14.

Secured to and engaged by pins l3 with the upper end of the sleeve 13 torotate therewith is a circular table I5, said table being retained soengaged with a screw and loose washer or keeper l3 The inner surface ofthe sleeve 13 is provided with an annular channel [6; and the spindlehas a lateral passage coinciding with said channel, there being anoutlet therefrom in the 50 sleeve with which a pipe is connected so thatwater under pressure coming into the chamber I I discharges through thepipe I! in all positions of the rotatable sleeve.

In order to provide for the scrubbing of various sizes and forms of wareand portions thereof the table I is provided with three sets of brushes,as best depicted or suggested in Fig. 3. Taking first the set in thelower portion of Fig. 3, it will be noted that the two brushes areelongated loops of twisted wire holding tufts of bristles. One of thebrushes, [8, is somewhat smaller than the other, l9, and each brush ismounted on a weighted block, as shown at 26 and 2| respectively, saidblocks being supported in a suitable frame 22 and hinged together byprojecting ears and a hinge pin at 23 so that when one brush islaterally tilted the other is likewise tilted in the opposite direction(see Fig. 5). As shown the said brushes mesh when in normal position.

In practice according to the construction shown on Fig. 3, if a tumbleris pressed in inverted position fully down on one of the said brushes toenter the tumbler the effect is to slightly separate the brushes withone brush bearing on the interior wall of the tumbler and the otherbearing on the exterior wall thereof. In all cases the brush selectedfor scrubbing is such that when the tumbler to be scrubbed is presseddown, the brush should be somewhat crowded in the tumbler to effect goodscrubbing contact.

Upon rotating the table while firmly holding the tumbler from rotationin the hand of the operator the effect is to cause the brushes to scrubboth the interior and exterior surfaces of the tumbler. When the tumbleris removed from the brush the weighted members in which they are rootedautomatically restore the brushes to closed or meshed relation.

Referring now to the set or group of three brushes 25, 26 and 27, asshown in the plan view Fig. 3, the brushes 25 and 26 are rooted in asingle block 28. The brush 25 is the smaller of the two and ofcylindrical form while the brush 26 is of loop form. The brush 25 isrooted centrally at 2511 in the said block 28 and the stems of theloop-brush 26 are rooted at two points 26 at opposite sides of the root25 as indicated in Fig. 7. The cylindrical brush 25 therefore stands ata meshing slant to the loop brush 26, as shown in Fig. 1. The block 28is supported by a plate 29 on the upper surface of the table in a radialslot therein, said plate 29 being provided with slots 30, 30, throughwhich set screws are passed to secure said brushes 25 and 2'6 inadjusted position in relation to the third brush 2?.

The third brush 2'! is rooted and supported, as seen in Figs. 1 and 7,in a weighting member or block 33 hinged at 3| between parallel bracketarms 32 secured to the upper side of the rotatable table and extend atthe lower side of the said table so that after a piece of the drinkingware has been placed on said brush 27 it is internally and externallyscrubbed in the same manner and with the same effect as hereinbeforedescribed in respect to that operation with the brushes l8 and 19. Thethree brushes are adapted for three different diameters of drinkingvessels.

At the right hand side of Figs. 1 and 3 there is shown a device forscrubbing the exterior of the bottom of a piece of ware such, forexample, a beer mug. In this construction there is a circular brushmounted stationarily on four posts 36, the latter being supported on aplate 31 that in turn is secured to a central tube 38 fixed in therotatable table. The other brush 39 of this device is shown as ofpine-tree form having a trunk or stem 3E: that is reciprocablevertically in the said tube 38. In order that said brush 39 shall exertpressure on the bottom of the mug, especially if it be concavedconsiderably upward, the trunk or stem of this brush has a pin 40extended through it with a coil spring 4| connecting each projecting endof the said pin with the plate 37 so as to hold the brush yieldinglyupward with sufficient force satisfactorily to scrub the mugs bottomwhen pressed downward on said brush. When the brush 39 is thus presseddown with a mug or other article to be scrubbed at its bottom externallythe end of the mug is at the same time encircled by the ring brush 35 sothat when the article to be cleaned is held firmly in the hand and thetable rotated, the said brushes exert a scrubbing effect, due to therelative rotation of the brushes in the ware, in the manner hereinbeforefirst described, except that the scrubbing action is in both horizontaland vertical planes.

It is, of course, desirable that water or other cleaning fluid be usedin connection with the operation of the brushes, and that the apparatusbe placed in a tub into which water or a sterile solution can besupplied. In Fig. l is illustrated, in broken lines, at 88 a tub inwhich the apparatus is placed, the said tub having an overflow hoseconnection at El, and a drain or clean out at 62. The said drainincludes an ordinary han dle 63 to operate an ordinary valve to controlthe drain and the overflow hose connection 6| provides for thecontingency of neglect to cut off Water after work is done. It is alsodesirable that the water or solution be directed into the region wherethe scrubbing is done and onto the brushes and the surfaces scrubbed andthe supply of water controlled as to time of its application.

The means for supplying such water consists of a pipe connected at itsdischarge end with the chamber ll, there being in said pipe a casing 46containing a valve for opening and closing said pipe and a spring 41 forautomatically moving said valve to closing position. Said valve has astem 48 projecting from the casing; and hinged at 49 near the valvecasing is an arm 50 having at its free end a roller 5| in constantcontact with the eccentric or cam l4 that rotates with the sleeve andtable [5. The pipe 52 that leads to the valve casing is extended to beconnected with any suitable source of water under pressure. If desired asterilizing agent can be supplied to the water in the tub.

There are as many of the pipes I! as there are pairs and groups of thebrushes, in this case there being three, said pipes being extendedupward through small holes in the table in which said pipes fit so thatthe pipes are held steadily in proper relation to the brushes.

According to the construction shown the water is substantiallysimultaneously discharged onto practically all the groups of brushes andcorrespondingly cut off according to the position of the valve, thelatter being controlled by the position of the eccentric or cam. Byreason of this construction the water may be cut off when the washing ofa piece of ware has been completed, and the brushes determined upon forapplication of another and perhaps different size of ware in theinterval when the water is cut off. It will be understood that inapplying a piece of hollow ware of the type of drinking glasses to abrush the pressure of the operators hand is first downward onto anappropriate brush and then in a lateral direction to cause rotation ofthe table and that this rotation of the table while the Ware is heldwithout substantially turning the ware on its axis causes relativerotation of the brushes in respect to the axis of the ware. In otherwords if the ware were not held the brushes would not rotate withrespect to the axis and surfaces of the ware.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

What I claim is:

l. A drinking ware washing apparatus including a horizontal freelyrotatable table, two brushes secured to the table in proximity to eachother in an erect and meshing position and at points offset from theaxis of rotation of the said table with the axis of said brushes bothlaterally remote from the axis of rotation of the table and betweenwhich brushes the wall of the drinking ware can be inserted, wherebywhen the table is rotated by pressure of the hand on the ware withoutsubstantial rotation of the ware a scrubbing action on the ware iseffected.

2. A drinking ware washing apparatus including a horizontal freelyrotatable table, two brushes secured to the table in proximity to eachother in an erect and meshing position and at points offset from theaxis of rotation of the said table with the axis of said brushes bothlaterally remote from the axis of rotation of the table and betweenwhich brushes the wall of the drinking ware can be inserted whereby whenthe table is I rotated by pressure of the hand on the ware withoutsubstantial rotation of the ware a scrubbing action on the ware iseffected, and means connected with said table whereby a spray of watercan be applied to said brushes during the rotation of said table.

3. A drinking ware washing apparatus including a horizontal freelyrotatable table, two brushes secured to the table in proximity to eachother in an erect and meshing position and at points offset from theaxis of rotation of the said table with the axis of said brushes bothlaterally remote from the axis of rotation of the table and betweenwhich brushes the wall of the drinking ware can be inserted whereby whenthe table is rotated by pressure of the hand on the ware withoutsubstantial rotation of the ware a scrubbing action on the ware iseffected, and means connected with said table whereby a spray of watercan be applied to said brushes during a portion of the rotation of saidtable.
